Re: crank pulley and pin

You can use a pulley from just about any late model subaru. Maybe you can get a stock one locally from someone who "upgraded" to a one piece or underdrive.

Re: crank pulley and pin

Re: crank pulley and pin

Does anyone besides me believe that if the bolt was torqued down a bit more the problem with the "key, pulley, etc" would never happen?
I bought a new Subaru legacy in 1990 and when it was time for the "40,000 mile, 40 weeks after I purchased it, service-timing belt, etc I took it to a dealer to do it to "preserve" the warranty. They said if I didn't the warranty would be void. A few thousand miles later, I had the "key-pulley" problem and they simply said it was pretty common.
That was the last time it went to the "experts".
300,000 miles later with the Legacy and about 160,000 SVX miles with removal and reinstalling the "big old pulley" no more problems, although I have removed and reinstalled the thing at least 20 times on various different motors.
However, I always torque it down pretty good... with a big break-over bar and a big mauler!
At least 460,000 miles later logic tells me when I do it like that, it "ain't" going anywhere... and it hasn't so far.

You might be on to something.
Maybe I should adopt your hammer method. Or I could stomp on the ratchet to give it enough "foot pounds"
I've had an aluminum pulley strip out after being in place for many years and I used the factory torque settings with a good torque wrench.

Re: crank pulley and pin

How about more normal torque and some thread locker ?

+1 on that. Prime cause is, not tight enough. Positive fix is mounting the key and pulley with a "lock tight pulley mount" product. This fills any space between the parts, that allow the movement to start. Should also be used on camshaft pulley keys and mounts.

Could we have pictures of the "Or I could stomp on the ratchet to give it enough foot pounds" alternate addition, please

Re: crank pulley and pin

Because I'd rather torque something to factory spec and lock it there with thread locker than overtorque something, possibly stripping the threads or snapping the head of the bolt off . Torque values are set by the engineers for a reason, and I use them where provided. A properly torqued bolt with threadlocker is not going to back out. IMHO, play between the woodruff key and the pulley is what chips and eventually elongates the keyway, not a loose crank bolt.

Yes defiantly. There is a lot of load on that key, it takes all the torsional forces that the crank send to the harmonic balancer. A small amount of backlash, when fitted, will grow to a knocking sound, and fail.

Using a product to fill this backlash will prevent this. Particular the cam shaft pulley fit, of a round key in a square grove.

Harvey.

Re: crank pulley and pin

What is the correct torque for the bolt?
